What does the Bible say about atonement and sacrifice?

In Scripture, atonement is central to understanding God's relationship with humanity. It is essential to recognize that no sacrifice made by man, including the blood of bulls and goats, could atone for sin (Hebrews 9:14). David's insistence to buy the threshing floor at a cost signifies the necessity of a true and costly sacrifice. Ultimately, God required a sinless sacrifice — His own Son, Jesus Christ, who offered Himself completely to meet the demands of divine justice. This act of atonement is what reconciles sinners to God, revealing the depth of God's grace and holiness.
